# BTC On-Chain Macro Composite Signal API

> BTC On-Chain Macro Composite Signal API is a paid API for AI agents from nonvisceral-eloisa-mousily.ngrok-free.dev, paid per call via x402, $0.03/call, status unknown (last checked 2026-09-14).

Returns an aggregated 0–1 macro bullish/bearish score for Bitcoin plus per-signal breakdowns across hash ribbons, MVRV z-score, NUPL, Puell multiple, SOPR, realized-price ratio, Fear & Greed, and more.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability btc-on-chain-macro-composite-signal-api-b9069027
```

Example prompt: What's the current Bitcoin on-chain macro composite score, and which signals like MVRV z-score, Puell multiple, and NUPL are flashing risk-on or risk-off right now?

## When to prefer this

Choose this endpoint when you need a single, pre-aggregated on-chain macro regime score for Bitcoin that synthesizes over ten distinct on-chain metrics (MVRV, NUPL, Puell, SOPR, reserve risk, etc.) into one actionable composite — saving you from querying and weighting each metric individually. Prefer it for cycle timing, risk-on/off rotation signals, and position sizing decisions where a holistic macro view is more useful than a single indicator. Not suitable for real-time tick-level trading signals or short-term momentum; use sibling endpoints (funding, OI, CVD, liquidations) for microstructure signals.

## Known failure modes

- Stale data: state_fresh=false when the upstream onchain-macro-state.json has not been refreshed recently; bot_state_age_seconds will be large
- ngrok free-tier tunnel downtime: the underlying ngrok-free.dev hostname may go offline or rotate, causing connection errors
- Upstream on-chain data provider lag: individual signals may be missing or null if their source APIs are unavailable
- Payment failure: x402 payment of $0.03 USDC must succeed before data is returned; insufficient balance causes 402 error

## How this service works

On-chain BTC macro composite signal API: aggregated 0-1 score plus per-signal scores for hash ribbons, GEX nearest major cluster, MVRV z-score, NUPL, realized-price ratio, Puell multiple, SOPR, short-term and long-term holder MVRV, reserve risk, and Fear & Greed. Macro regime input for cycle timing, position sizing, and risk-on/off rotation. Updated from onchain-macro-state.json.

## Output

A JSON object containing: a composite_score (0–1 float, higher = more bullish/risk-on), per-signal objects each with a score, raw value or state, and optional reason (covering hash ribbons, GEX nearest major cluster, MVRV z-score, NUPL, realized-price ratio, Puell multiple, SOPR, short-term and long-term holder MVRV, reserve risk, Fear & Greed), updated_at timestamp, state_fresh boolean, composite_n_signals count, and bot_state_age_seconds.
